Background : Juvenile idiopathic arthritis (JIA) is one of many chronic diseases in children. The common types of JIA are oligoarticular and polyarticular. Fifteen to 27% children with JIA will have joint damage that lead to disability and decreased quality of life. The aim of this study is to investigate the type of JIA as a risk factor of severity of disability based on CHAQ.
Material : We conducted case-control study in children with JIA who came to pediatric immunology ambulatory clinics at Dr. Sardjito General Hospital Yogyakarta on April-May 2018. Diagnosis and classification of JIA were based on ILAR criteria. Physical function was measured using the CHAQ. Subjects were divided into 2 groups: CHAQ ?0.5 (mild disabilty) as a control group and CHAQ >0.5 (moderate to severe disability). Each group was analyzed by type of JIA (oligoarticular and polyarticular). The statistical data were analyzed by chi-square, and the significance level was set as P <0.05.
Results : We included 33 JIA children (10 boys and 23 girls) with mean of age 10.08 years (1.58–17.91). Fourteen children (42.4%) had mild disability and 19 children (57.6%) had moderate to severe disability. Eighteen children (54.5%) had oligoarticular JIA and 15 (45.5%) children had polyarticular JIA. Twelve polyarticular JIA children (80%) and 7 oligoarticular JIA children (38.8%) had moderate to severe disability. The risk of moderate to severe disability outcome was significantly higher in polyarticular JIA (OR 6.28, 95% CI 1.29-30.53, P 0.017).
Conclusions : The risk of disability based on CHAQ in polyarticular JIA had significantly higher than oligoarticular JIA.
